Patent JP-H0698584-A (JP)
Title: Sensorless motor controller
Inventor: SAKURAI TETSUJI
IPC: G11B19/20
Filed: 1992-09-14
Abstract: PURPOSE:To obtain an expected revolution when a forced rotation is finished and realize the stability of the generation of a counter electromotive force when a sensorless motor(SM) is started by a method wherein the excited phase switching control of the SM is performed in accordance with a predetermined constant accelera tion curve to make the SM rotate forcibly. CONSTITUTION:A motor control part 2 puts a phase number counter A into an initial state and outputs an excited phase control signal 5 of an Ath phase and, further, calculates a phase time of the Ath phase in accordance with a predetermined constant acceleration curve and waits for a period of one phase time. Then the motor control part 2 gives an increment to the phase number counter A and outputs the excited phase control signal 5 of the next phase. The motor control part 2 compares the value of the phase number counter A with a phase number B which is predetermined by the characteristics of the motor. If the predetermined number of phases of a forced rotation are finished, the start of the steady rotation of the rotor is judged in accordance with a rotor position signal 7 given by a rotor position detector 4. If the rotor is made to rotate and a stable counter electromotive force is generated, the rotor position signal 7 is changed to an expected output, so that the start of the steady rotation of the rotor can be judged.

Title: Testing system for dma transmission control circuit
Inventor: HICHIHARA MASAAKI
IPC: H04L69/40
Filed: 1986-11-13
Abstract: PURPOSE:To omit a large-capacity memory and a large quantity of test data and to decrease the test facilities together with reduction of the test cost, by checking whether the number of words of the received transfer data is equal to the prescribed number of words or not and at the same time having a cyclic redundancy check of the transfer data. CONSTITUTION:When the transfer data transmitted from a DMA transmission control circuit 1 is received by a DMA reception control circuit 2, the received data is not stored and the number of transferred words of the data is written into a transfer word number counter 3. Then it is checked whether the number of said transferred words is equal to the prescribed number of words or not. At the same time, the CRC (cyclic redundancy check) arithmetic of the data is carried out by a CRC arithmetic circuit 4. This arithmetic result is written to a CRC arithmetic result register 5 for check of normalcy of the circuit 1. Thus it is possible to omit a large-capacity memory which stores the transfer data and also to finish the CRC in a short time together with omission of a large quantity of test data. As a result, the reduction of cost is attained with the test facilities and test itself.
